CHAIR Filed March 4 ATTORNEYS Patented Aug; 16, 1932 UNITED STATES PATENT OFFICE My invention relates to a new and improved chair.

One of the objects of my invention is to provide a new and improved chair which shall be extremely comfortable, which can be utilized as a rocker, and which is also adapted for the use of invalids.

Another object of my invention is to provide a chair of an improved type, having a pair of wheels by means of which the chair can be readily moved from place to place.

Another object of my invention is to provide a chair of this type which shall be properly balanced, so that the chair can be conveniently transported or used as a rocker.

Other objects of my invention will be set forth in the following description and drawing which illustrate a preferred embodiment thereof, it being understood that the above general statement of the objects of my invention is intended to merely generally explain the same and not to limit it in any manner.

Fig. 1 is a perspective view.

Fig. 2 is a side elevation which diagrammatically illustrates how the chair is moved from place to place by means of its Wheels.

Fig. 3 is a rear elevation of Fig. 2.

Fig. 4 is a detail plan view of the foot portion of the chair.

The chair comprises a frame made of any suitable material, which may be light wood such as bamboo and the like. The chair comprises a foot portion 1, arm portions 2, and a back rest 3. The chair may be provided with removable cushions C of any suitable type, or it may be suitably upholstered. The bottom of the frame comprises rocker portions 4, and the rear of the frame is provided with a pair of wheels lV, mounted upon an axle 5, whose bearings are suitably connected to the frame of the chair by means of braces 6 and 7 The front or foot portion of the chair is provided with a bar 8 which is made of iron or other relatively heavy material, so as to counter-balance the weight of the wheels l/V and of the axle 5.

It is not absolutely necessary to have the wheels W although these are desirable in order to enable the chair and its occupant to be conveniently transported, so that the improved chair is especially adapted for the use of invalids. The back rest 3 may have any desired angle, justable in the well known manner so that it can be tilted to a higher angle than that shown in the drawing herein.

When the chair occupies the position shown in Fig. 1, it is a ing chair which can also be utilized as a rocker. In the position shown in Fig. 2, the foot portion of the chair has been raised so tvlxi at the chair rests solely upon the wheels the chair tipping backwards if it is used as a rocker, and that the construction is extremely simple and strong.

It will be noted that the curved rocker members 4 that portion of the frame upon which the cushions are located. This portion of the frame may be conveniently designated as the supporting frame. The rocker members are continuously curved and their ends extend up to, and are directly connected to the rigid supporting frame. As shown in Fig. 3, the axle is also connected to said rigid supporting frame.

The rigid supportingframe has an intermediate seat-section, a front leg-supporting section, and a rear back-rest section. The curvature of each rocker member in front of the seat portion is less than the curvature thereof under the seat-section and the back- 85 rest section. Likewise, each rocker member is wholly located under and between the backrest section and the leg-supporting section, so the wheels W can be located close to the rear end of the supporting frame. makes it possible to support the person using the device in a substantially horizontal position when the device is being wheeled, as shownin Fig. 2. In this ions of the leg-supporting portions are upwardly and forwardly inclined. Likewise, the body of the person using the device is insubstantially horizontal position when the device is at rest, as shown in Fig. 1. This 101 and it may be made adas comfortable loung- It is clear that there is no danger of are connected at both ends to This position the cushg5 construction may be defined by stating that the supporting frame is in substantially hon zontal position when the device is at rest.

When the chair is in its normal position [1 shown in Fig. 1, the wheels W are above the support upon which the chair rests. At this time the wheels W act to limit the rearward rocking movement of the chair.

I have shown a preferred embodiment of 10 my invention, but it is clear that numerous chan es and omissions could be made without eparting from the spirit of my invention.

I claim:

II A chair comprising a rigid supportinlgl frame, rocker members located underneat said rigid supporting frame and connected theretorespectively at the forward and the rear end thereof, said rocker members being I located wholly between the ends of the frame,

said frame comprising a leg-supporting portion and a 'seat ortion and a back-supporting portion, an wheel means connected to the rocker members said wheel means being ll located normall in a plane above the normal support-ing sur ace rearwardly thereof, and

em rocker member comprising rear and front portions, the curvature of the rear portion being greater than the curvature of the 80 front portion, whereby said supporting frame may be tilted rearwardly to brmg said wheels in contact with the supporting surface, thereby forming a wheeled chair or stretcher.

In testimony whereof I aflix my signa- 86 ture.

CONRAD BIELECKY.
